Total Mercury in Heron and Egret Eggs and Excreta
Hoffman, Robert D.
Complete clutches of great blue heron (Ardea herodias), black-crowned night heron (Nycticorax nycticorax), and great egret (Casmerodius albus) eggs were collected along with excreta from nesting colonies in southwestern Lake Erie during the 1973 and 1974 breeding seasons and analyzed for total mercury content. Mercury levels in eggs ranged from 0.04 to 0.47 ppm. Mercury concentrations in excreta ranged from 0.09 to 0.48 ppm.

The Effects of Immunologically Active Amino Acid and Amino Sugar Derivatives on Transport Systems ofS37 Ascites Tumor Cells
Lewis, Neil J.; Matthews, Richard H.; Filppi, Joyce A.; Rheins, Melvin S.
N-a-benzyloxycarbonyl-L-lysine had been shown to possess an immunosuppressive effect, and N-acetyl-D-glucosamine an enhancing effect on the production of IgG and IgM in mice. We studied mechanisms for these effects including a) possible specificity of these agents for cells of the immune system, b) effects of the test compounds on amino acid transport, protein synthesis and/or the rate of growth of some other cellular system. The study system chosen was the mouse S37 ascites tumor cell. Neither compound exerted any effect upon protein synthesis in the S37 cells, or upon survival time of mice bearing the S37 ascites tumor. The effects of the compounds upon antibody production were, therefore, considered to be selective to cells of the immune system rather than general for any actively-metabolizing cells of the mouse. N-a-benzyloxycarbonyl-L-lysine did exhibit selective affinity for the L and A amino acid transport systems of the S37 cells. This effect modified previous concepts of the specificities of the two principal neutral amino acid transport systems.

Growth of Thioploca Ingrica in a Mixed Culture System
Maier, Siegfried
Previously, Thioploca ingrica had not been grown in the laboratory and observation of the organism was limited to specimens taken directly from natural mud samples. The method described here makes laboratory cultivation of T. ingrica in mixed culture possible. The medium consists of low concentrations of extracted hay, water, and mud with its natural bacterial flora. Four weeks after the hay and mud were mixed, the medium was inoculated with T. ingrica washed from Lake Erie mud. It was found that the higher the concentration of hay, the lower the success rate and the longer the elapse of time before the organism established itself. Conversely, longevity of a successful culture improved with higher concentrations of hay. The growth of the organism in the flasks was observed in situ with an inverted microscope.

Descriptive Mineralogy of Pugh Quarry, Northwestern Ohio: Barite and Celestite
Parr, David F.; Chang, Luke L. Y.
Two sulfate minerals, barite and celestite, were identified in the Devonian rocks at Pugh Quarry. The barite occurs commonly as rosette-like clusters with wide variety of colors and crystal habits. Unusual features include paired crystals and hollow crystals. The former consist of two barite crystals growing parallel with each other on the dolostone matrix, and the latter only of a thin wall of barite commonly marked by cross striations. Celestite crystals have two different colors. The grayblue and blue crystals are prismatic to blocky and occur as well-formed individuals, whereas the colorless and white crystals are tabular to bladed and occur as distinct individuals and as compact clusters.

Nesting of Red-Winged Blacbirds in Cattails and Commed Reed Grass in Mentor Harsh
Bernstein, Neil P.; McLean, E. Bruce
During summer 1976, a study of habitat selection by the red-winged blackbird, Agelaius phoeniceus, was conducted. Mentor Marsh near Mentor, Ohio was chosen because of its unique geologic and botanical history. A swamp forest prior to 1959, the area is now a marsh composed of Typha latifolia, T. angustifolia, and Phragmites australis. Preferences of A. phoeniceus for each of these plants were investigated, and T. latifolia was significantly most chosen. Presumed advantages include rigidity, easy nest accessibility, and wide spacing to facilitate nest defense. Additional features of habitat selected such as available perches, proximity of open water, and edge effect were investigated. If rapid succession to monodominant stands of P. australis continues at the present rate, the nesting red-winged blackbird population may decrease sharply.

Degradation of 16S RNA in Thermally Injured Staphylococcus Epidermidis
DiLella, Anthony G.; Sobota, Anthony E.
Exposure of Staphylococcus epidermidis to sublethal temperatures produced a temporary change in the salt tolerance. After sublethal heat treatment at 52 °C for 20 min, 96% of the viable population was unable to reproduce on media containing 7.5% NaCl. The thermal injury results in alterations in the cell membrane allowing leakage of RNA into the heating media. Polyacrylamide gel electrophoresis revealed 16 S ribosomal RNA to be extensively degraded in thermally injured cells, whereas 23 S and 5 S RNA were unaffected. When the thermally injured cells were incubated at 37 °C in Trypticase Soy Broth, 16 S RNA was regenerated accompanied by a return of salt tolerance in the absence of DNA synthesis. In the presence of high concentrations of magnesium, cellular leakage of RNA was suppressed and the degradation of 16 S RNA was not observed in thermally injured cells.

Oral Contraceptives and Exercise
Mostardi, Richard A.; Woebkenberg, Nancy; Jarrett, Marcia T.
Twelve college women, 5 naturally cycling and 7 on oral contraceptives, participated in a study to determine if oral contraceptives have an effect on selected hematologic and metabolic variables. The women worked at 2 workloads on a bicycle ergometer: 50% and 90% of their maximal aerobic capacity during 3 phases of the menstrual cycle, post mensus, ovulation, and mid-luteal. Within group differences were examined to determine if one time of the month was more suitable for doing submaximal or near maximal work, and between group differences were examined to determine the effects of oral contraceptives. Within the 2 groups, there were no significant differences for any variables. Between group differences were associated with higher heart rate and ventilation values for the women on oral contraceptives when the workloads were near maximal.
